BOILER AND TUBE CLEANER.

Application led September 23, 1910. Serial No. 583,335.

To all whom it may concern:

Be it known that I, Ricrnmn W. HAM/inn, a citizen of the United States, and resident of St. Louis,Missouri, have invented certain new and useful Improvements in Boiler and Tube Cleaners, of which the following is a specication containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in boiler and tube cleaners, the object of my invention being to construct a cleaner for boilers and boiler tubes which is permanently fitted in the boiler setting and the op eration of which requires only the supplying thereto of a fluid under pressure.

A further object of my invention is to construct a cleaner of the class described which will simultaneously discharge a fluid under pressure against a number of the tubes which are placed in such ositions relative each other as to prohibit t e use of vertical cleanin tubes.

For t e above purposes my invention consists in certain novel features of'construc- .tion and arrangement of parts as will be hereinafter more fully described, pointed out in the` claims and illustrated by the accompanying drawings, in which- F1gure'1 is an elevation of a boiler setpped with my improved. boiler tube cleaners; ig. 2 is an enlarged, transverse,

.sectional 4elevation taken on the line 2-2 of Fig. 1; Figz is an enlarged, detail, sec- 1 tional elevation of aportion of the setting,-

i` detail view illustratin a'l portion of the boiler and a number of the tu es showing the arrangement of my imroved' cleaners and which is taken on the ine 3T3 of Fig. 1;l Fig. 4t is an enlarged, acoupling between two header or manifo d sections; Fig. 5 is a view illustrating the arrangement of the cleanertubes relative the header; and Fig. Gis a detail view illustrating the arrangement of the perforationsin the header for discharging a iuid against vthe boiler.

Referring by numerals to the accompany-4 ingldrawings: lfdesignates the boiler setting, 2 t

eboiler, 33 water legs and 4 the boiler tubes, all of which are-or may be of ordinary construction.. A

'5 designates the usual tiling arran ed over the lowermost 4row of tubes 4, .and 6 designates the tiling arranged over the upb5 permost row cgt the tubes.

7 and 8 designate the forward headers and 9 and 10 designate the rearrnost headers. These headers are each provided with a.

number of tapped openings 1l. arranged to 60 support, in communication with the headers, the cleaner pipes 12. As shown, the first of the series of the pipes 12 is connectedl with the header by a reducing coupling 13,

the second pipe 12 being connected with the 65 header by an Lcouplingl4 and a nipple 15. By this arrangement the pipes may be held in differentplanes relative the header as required to cross them as shown.

` At intervals throughout the lengths of the pipes 12 are arranged the jet openings' 16, the openings being spaced so ythat when placed in position the jet openings will be between the boiler tubes. By placing a series of pipes 12, provided with such openi ings, all surfaces of all -the boiler tubes will -be simultaneously'..cleaned, the cleaning be" ing in the direction of the natural draft of the furnace,

Where there ployed, as illustrated, one of the rearmost headers is provided with a series ofopenings 17 arranged, as shown in Fig. 6 to dis?l charge a iiuid under pressure against the ,boiler proper and also to cleanse the upp'erfggf surface of the tiling 6 on top of the tubes. l At the forward end of the furnace the cleaning apparatus' shown is for the purpose of cleaning that portion of the boiler notV reached by the rearniost header and for thefa purpose of cleaning the tiling 5, the tierening pipes, suspended from the forward head; i ers, being provided with jet openingsonly "at 'j their lower ends adjacent the tiling.'

When two or more headers are e they are connected by a T-coupling 18, the one header section being internally threaded and a plug 19 seated therein. The header to one side, of said coupling -is connected with a supply pipe 20, leading from a source of 100 steam or other fluid under pressure, by the pipe 21 and the header to the other'side of said T-coupling being connected with the supply pipe by a pipe 22, each of which pipes 1s provided with valves such as 23 for 10li admitting steam from the pipe 2 0.

In addition to the openings 17 in the headers there are openings 24 which discharge In' is a. multiple header em- 'i line with the tiling G. These openings are at intervals throughout the entire lengths of the headers.

It is obvious that when a boiler setting is lequipped with the cleaners as shown all points* within the setting, including the loiler or drum and the boiler tubes, may be thoroughly cleansed and, as previously described, this cleansing is accomplished without the employment of movable parts.

By reason of the construction employing independently connected header sections different parts of the setting may be independently cleaned, also, by reason of the independent header sect-ions, the headers may by constructed of a size convenient to handle in assembling and setting up.

By reason of the force of fluid under pressufre all arts of the setting may be thoroughly cleansed vwithout scrapers or other extraneous implements.

By so dividing the cleaner pipes the combined areas of their jet openings, that is the jet openings connected with a single header section, will not be in excess of the capacity of the supply pipe.

-While I lia-ve shown only two header sections, each of which has an independent connection with the steam pipe 20, it is obvious that when it is desired to equip a furnace of (greater width it will be only necessary to ad another header and its connection with the steam supply pipe.

` I claim:4

1. In a' device of the class described, a sectional header, a connection between each section of said header and a supply of fluid under pressure, a number of pipes connected with each section of said header, which pipes are arrangedl between diagonal rows of the boiler tubes, there being jet openings in said pipes.

2. In a device of the class described, a header, a connection between said header landJ a supply of fluid under pressure, pipes connectedwith said header, which pipes are arranged between the boiler tubes, a number of said ip'es crossing other pipes so 'as to reach'allof the tubes, there being jet openings in each of said pipes.

3.*In a device of the class described, a

header, a connection between said header and a source of Huid supply under pressure, pipes connected with said header and arranged between the boiler pipes, a number ol the pipes crossing other pipes so as to reach all of said. tubes, there being jet openings in said pipes at intervals and jet openings in the header arranged to discharge onto the boiler and parts of the settin 4l. In a device of the class descri ed, a

header comprising a number of non-cont municating sect-ions, means for independently connecting the different sections with a source of fluid supply under pressure, pipes connected with the different sections of the,

header and arranged between the .tubes ofv the boiler, there being jet openings in said pipes arranged to discharge in la direction approximately parallel with the boiler tubes.

5. In a device of the class described, a header, a connection between the header and a. source of fluid supply under pressure, a number of pipes connected with said header, which pipes are extended between diagonal .rows of boiler tubes, a number of which pipes are crossed as required to reach all of the tubes, and connections between said pipes and the header for holding said pipes in different planes laterally removed from the header, there .being openings in said pipes' at intervals'.

6. In combination with a boi-ler, b oiler' tubes and their setting, of headers arranged at either end of the boiler setting independent connections with each header and a source of fluid supply under pressure, pipes connected with said headers and arranged between the boiler tubes, there being jet, openings in said pipes arranged to discharge in a direction approximately parallel with the boiler tubes, and there being jet openings in said headers, for the purposes stated. p

In testimony whereof, I have signed my name to this s ecication, in presence of two subscribing witnesses.
